A nurse is caring for a client who has a cardiopulmonary arrest. The nurse anticipates the emergency response team will administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?
Magnesium
Sodium bicarbonate
Epinephrine
Atropine
The Correct Answer is D
Choice A Reason: This is incorrect because magnesium is not a medication for symptomatic bradycardia. Magnesium is a mineral that regulates muscle and nerve function, blood pressure, and blood sugar levels. Magnesium can be used to treat conditions such as torsades de pointes, eclampsia, or hypomagnesemia.
Choice B Reason: This is incorrect because sodium bicarbonate is not a medication for symptomatic bradycardia. Sodium bicarbonate is a substance that neutralizes acids and bases and regulates the pH of the blood. Sodium bicarbonate can be used to treat conditions such as metabolic acidosis, cardiac arrest, or overdose of certain drugs.
Choice C Reason: This is incorrect because epinephrine is not a medication for symptomatic bradycardia. Epinephrine is a hormone that activates the sympathetic nervous system and increases the heart rate, blood pressure, and blood flow to the muscles and brain. Epinephrine can be used to treat conditions such as anaphylaxis, cardiac arrest, or severe asthma.
Choice D Reason: This is correct because atropine is a medication for symptomatic bradycardia. Atropine blocks the action of the parasympathetic nervous system and increases the heart rate and conduction. Atropine is a medication that blocks the action of the parasympathetic nervous system and increases the heart rate and conduction.
Symptomatic bradycardia is a condition where the heart rate is slower than normal and causes symptoms such as dizziness, fatigue, chest pain, or fainting. Atropine can be used to treat symptomatic bradycardia by stimulating the sinoatrial node and the atrioventricular node, which are the natural pacemakers of the heart.

Correct Answer is B
Explanation
Choice A: Ask the client to shrug his shoulders against passive resistance is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve XI, which is the accessory nerve. The accessory nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in shoulder and neck movements.
Choice B: Instruct the client to look up and down without moving his head is an assessment that will give the nurse information about the function of cranial nerve III. Cranial nerve III is the oculomotor nerve, which innervates four of the six extraocular muscles that control eye movements. The oculomotor nerve also controls pupil size and lens shape. By instructing the client to look up and down without moving his head, the nurse can assess the ability of the oculomotor nerve to move the eyes vertically and adjust to different distances.
Choice C: Observe the client's ability to smile and frown is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve VII, which is the facial nerve. The facial nerve innervates the muscles of facial expression, which are involved in smiling, frowning, blinking, and other facial movements.
Choice D: Have the client stand with his eyes closed and touch his nose is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve VIII, which is the vestibulocochlear nerve. The vestibulocochlear nerve innervates the inner ear and is responsible for hearing and balance. By having the client stand with his eyes closed and touch his nose, the nurse can assess the ability of the vestibulocochlear nerve to maintain equilibrium and coordination.
Correct Answer is C
Explanation
Choice A: Hct 45% is not a value that the nurse should report to the provider. Hct, or hematocrit, is the percentage of red blood cells in the total blood volume. The normal range for Hct is 37% to 51% for men and 32% to 45% for women. Hct 45% is within the normal range and does not indicate any abnormality.
Choice B: Platelets 160,000/mm³ is not a value that the nurse should report to the provider. Platelets, or thrombocytes, are cell fragments that help with blood clotting and hemostasis. The normal range for platelets is 150,000 to 450,000/mm³. Platelets 160,000/mm³ is within the normal range and does not indicate any abnormality.
Choice C: WBC 1,700/mm³ is a value that the nurse should report to the provider. WBC, or white blood cells, are cells that fight infection and inflammation. The normal range for WBC is 4,500 to 11,000/mm³. WBC 1,700/mm³ is below the normal range and indicates leukopenia, which is a low number of white blood cells. Leukopenia can be caused by various conditions, such as viral infections, autoimmune disorders, bone marrow suppression, or chemotherapy. Leukopenia can increase the risk of infection and sepsis and requires prompt evaluation and treatment.
Choice D: Hgb 14.7 g/dL is not a value that the nurse should report to the provider. Hgb, or hemoglobin, is a protein in red blood cells that carries oxygen to the tissues. The normal range for Hgb is 13.5 to 17.5 g/dL for men and 12.0 to 15.5 g/dL for women. Hgb 14.7 g/dL is within the normal range and does not indicate any abnormality.
